Q1. The period of oscillation of an object in a frictionless tunnel running through the Earth is 84.3 min. What is the time of oscillation of an object in a similar tunnel on the Moon? (RE= 6.37 x 106 m; RM=1.74 x106m; ME = 5.98 x 1024kg; MM = 7.36 x 1022 kg)
Q2. A basketball player who is 2.00 m tall is standing on the floor 10.0 m from the basket. The height of the basket is 3.05 m. He shoots the ball at θ = 45.0° from the horizontal with an original speed u. Imagine that the ball goes through the hoop without striking the backboard and air resistance is negligible.
